Personal music laser show toy system

ABSTRACT

The invention relates to a toy for a laser beam pattern that is controlled by a stereo output from music with the ability to control the starting pattern by the user. The above system provides a unique small visual entertainment music amplifier system toy that operates on batteries as well as AC adapter output.

BACKGROUND OF INVENTION

The present invention relates to a toy as a music laser show for aportable media player, and more specifically to a laser pattern that iscontrolled by music with said pattern adjustable option for the user.The present invention provides a means to use multiple lasers and abackground laser diffraction matrix pattern to visually make theappearance of the laser patterns to float in space.

Laser shows are well known prior art and are controlled by mirrorsmounted on motors. There are numerous laser show entertainment systemsavailable today and quite expensive and not for portable media playersand not as toys. One device known for generating light patterns is LASERONE™ FX machine. This machine generates various patterns with a laseronto a 1st rotating mirror that in turn reflects this beam onto a secondrotating mirror. The process requires a size increase in the secondmirror to accommodate the angular reflection from the 1^(st) mirrorthough there are drawbacks of the results.

Prior Art exists which addresses the issue of large angular reflectionswith a circular arrangement of mirrors and beam crossing to tighten theangle of incidence and reflection as to fix the drawbacks of the LASERONE™ FX machine. Both embodiments control the speed of motors to producea pattern which is well known art from the 1970s. Other processes thathave been deployed is to attach audio to change patterns generated by alaser beam incident and reflection through the use of membranes attachedto mirrors or motors.

While prior art exists for the purchase of laser entertainment systemswith most having complex apparatus for the movement of mirrors there isno compact inexpensive personal laser entertainment system availablethat can produce a music controlled pattern that appears to float inspace using batteries and/or an AC adapter designed to be connected to aportable media player such as an iPod™ from Apple Corporation.Furthermore, there has not been a simplification of the use of the wellknown art of using motors connected to an audio input to produce a verysmall cost effective battery operated toy.

In this respect, the Personal Music Laser Show Toy System inventionsubstantially departs from the conventional design of the modern daypurchasable system prior art for over 30 years and in doing so providesan inexpensive new entertainment system toy for a portable media player.

DETAIL DESCRIPTION OF THE INVENTION

Referring to FIG. 1 a block diagram is shown, at 100 is a 6-9 v powersupply to voltage regulators 200 thru 600. At 600 is a voltage regulatorfor a stereo amplifier at 700. At 700 the amplifier has one stereooutput channel 750 to OP amp adder 2 at 1100 and another stereo outputchannel 775 to OP amp adder 1 at 1000. The OP Amp adders 1000 and 1100are used to combine voltage from the amplifier 700 outputs 775 and 750to the motors 1200 and 1300 respectfully.

At 1000 is OP amp adder 1 which adds voltage from Voltage Divider Motor1at 800. Voltage Divider Motor1 at 800 divides voltage from Motor 1Voltage regulator at 200. At 1100 is OP amp adder 2 which adds voltagefrom Voltage Divider Motor2 at 900. Voltage Divider Motor2 at 900divides voltage from Motor2 Voltage regulator at 300. Voltage regulator200 and 300 are user controlled voltage regulators which enable the userto control the initial speed of the motors. At 400 thru 500 a number ofLaser Voltage regulators can be provided taking power at 100 to supplylasers.

At 1250 is a DPDT (double throw double pole switch) for the polarity ofMotor 1 at 1200 to change the direction of the motor by the user. At1350 is a DPDT for the polarity of Motor 2 at 1300 to change thedirection of the motor by the user.

Referring FIG. 2 a is a schematic diagram of component and values usedto construct a working embodiment. One skilled in the area can see thatthe circuit design can be used to create the embodiment and is theworking model.

Referring to FIG. 2 b, is a schematic diagram of component and valuesused to construct a working embodiment with block diagram areas inreference to FIG. 1.

Referring to FIG. 3 a is a bottom level circuit board design for theembodiment. Referring to FIG. 2 b is a top level circuit board designfor the embodiment. One skilled in the area can see that the circuitboard is designed to enable sufficient heat sinking and connection ofcomponents for optimal use and minimal production cost. The circuitboard is 120 mm by 64 mm and dictates and provides a compact productionof the embodiment to fit within this size.

Referring to FIG. 4 a is a diagram of the laser optics design to fitwithin the circuit board design area in FIGS. 3 a and 3 b of 120 mm by64 mm. Referring to FIG. 4 a, the figure is labeled Left, Right, Top,Bottom for reference points.

At 100 a normal is defined and at 200 a motor is placed on the normalwith axis along the normal at 100. A 25 mm round front surface mirror at210 is mounted perpendicular to the motor axis at 200, this location isreferred to as coordinate (0,0). At 200 the motor body is left of thefront surface mirror at 210.

At 300 another normal is defined which is parallel to the normal at 200.Normal 300 is 21.5 mm above the normal at 100. At 400 a motor is placedat the normal at 300 in which the motor's perpendicular axis is 59degrees±2° to this normal at 300. The motor at 400 has a 25 mm roundfront surface mirror at 410 mounted perpendicular to the motor axis, asa result the mirror at 410 is 59 degrees±2° from the normal at 300. At400 the motor body is right of the front surface mirror 410. At 400 themotor mounted front surface mirror at 410 front surface is facing and 40mm horizontal distance from the front surface mirror center at 210mounted on the motor at 200 along the normal 100. At 210 the frontsurface mirror front surface is facing 410 the front surface mirrorfront surface.

At 500 a laser is placed right 23.5 mm horizontal distance from themotor mirror 210 on normal 100. The laser at 500 is 28 degrees±2° fromthe normal essentially 12.5 mm below the normal 100. The laser at 500 ispointing toward the front surface mirror at 210. The laser at 500 mustbe 28 degrees±2° from the normal to allow fine angle adjust if neededand at least 23.5 mm from the mirror as to allow another laser at 600which is perpendicular to the normal at 100 to be placed. The laser at600 is used to provide a matrix diffraction grating. Optimally, at 500 agreen laser should be used and at 600 a violet blue laser should beused. This combination will provide the appearance to the user of thepattern created from the laser at 500 (green) to appear floating inspace.

Referring to FIG. 4 a, at 200 a motor has mounted a 25 mm front surfacemirror 210 and at 400 a motor has mounted a 25 mm front surface mirror410. The motors 200 and 400 are mounted as to have the axis 20 mm inheight for clearance for the mirrors 210 and 410 to spin respectfully.At 500 a laser (green) is shown and its height is 20 mm as to strike themirror 210 and 410 close to center.

At 600 is a laser at height zero. The motors at 200 and 400 are highenough as to allow for the laser 600 to be placed at height zero and notblock the laser beam from laser 500 to strike the mirrors at 210 and410. At 500 a 5 mw Class 111 b laser is to be recommended as it isrelatively safe for toy operation. Alternatively at 500 a Class II 1 mwgreen laser could be used which is safer. At 600 a Class IIIb 10 mwViolet-Blue laser (405 nm) is recommended inline with a matrixdiffraction grating at 700 and should produce a relatively safe patterndue to the dispersion. Optionally the motors at 200 and 400 can providefan blades for air flow to enable cooling if needed.

Referring to FIG. 4 b, a beam combiner at 800 can be used to add anotherlaser at 900. The laser at 400 should be pulled back along the incidenceaxis to the normal at 100 to mount the beam combiner at 800. At 900another laser is added which incidences to the beam combiner at 800. At900 a red laser (650 nm) could be used to add another color.

Referring to FIG. 5 at 5000 is a diffraction matrix that is produced bythe embodiment referring to FIG. 4A by laser at 600. Referring to FIG. 5at 5100 is a hypotricoid that is produced by the embodiment referring toFIG. 4 a by laser at 500. Referring to FIG. 5 at 5000 the diffractionmatrix color is optimally chosen to be 405 nm to 488 nm. Referring toFIG. 5 at 5100 the hyptrichoid color is optimally chosen to be 540 nm.The aforementioned optimal color combinations will enable the user toperceive the hypotricoid in FIG. 5 at 5100 to be floating in space.
